Main welding process parameters of ERW steel pipe



According to the production process, we know that there are lots of processes for the manufacture of ERW steel pipe. And here are some main welding process parameters during ERW steel pipe’s making.
1. Input power: input power control is an art for steel pipe’s production. If there is no enough input power, the edge of the strip cannot be completely melted.
2. Production speed: like the input power, we should make the right speed for ERW steel pipe’s making too. If the speed is too fast, the input heat is insufficient, and the solid oxide at the end can not be extruded to form a low-temperature welding defect
3. Opening angle: different angle would lead to different shape for steel pipe. So that we should take control for the opening angle during production.
4. Welding pressure: If the welding pressure is not enough, the weld lines on the two sides of the streamline of the metal structure are not obvious, and the welding strength does not meet the requirements.
5. The position of the induction coil: we should take control of the induction coil too.

Application range of high frequency vertical ERW steel pipe

In both low and high pressure environment, we should obtain the legal steel pipe from seamless steel tube,   ERW steel pipe   and   SSAW steel pipe for long-term life service.Under this situation, we should figure out the characters and main application environment for different steel pipes. Today, we would have an introduction for application range for high frequency longitudinal ERW steel pipe. 1. Oil, natural gas convey: Municipal gas transmission, long distance transportation of oil and natural gas would under the help of high frequency longitudinal ERW steel pipe. 2. Casing and tubing: This is another area we can count on ERW steel pipe. There is only seamless steel pipe can hold on this duty. However, with the high technology's development, now we can use ERW steel pipe to replace it. 3. Constructional structural pipes: No matter round, square or rectangular, we can use ERW steel pipe for frameworks of super malls, theater, airports, bridges and so on. ...

Testing explanation for steel pipe

In order to give customers secure steel products, such as seamless steel pipe,  ERW steel pipe  and so on, Tianjin Xinyue Steel Group would do various tests before the finally step of selling. Our steel pipes’ tests covers from Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test, Blow Test, Impact Test), Exterior Size Inspection, Hydrostatic Test to X-ray Test. Today, we would like to have a details introduction to Hydrostatic Pressure Testing. Hydrostatic Pressure Testing: Hydrostatic test is a test which coming after the pressure vessel is manufactured. Manufacturers would add appropriate amount of water to the vessel in order to test the macroscopic strength of the vessel (if it is deformed too much) and the sealing point and welding before the newly installed vessel 3 is used or entered.
